Dimeadozen is still accessible here. But then they won’t handle anything that’s ever been officially released, and they also run a list of not-allowed venues and artists who have requested to be blocked.

Its a box which you can plug into your tv, to turn it into a ‘smart’ tv if it isn’t already. It means the tv has access to the internet, and you can watch stuff which isn’t terrestrial broadcasting. A Sky TV box is a sort of kodi, as are the Amazon products, and the Roku/NowTV boxes.

‘Kodi’ boxes grew out of the ability of X-box games consoles to have third-party software installed. If the box is described as ‘fully-loaded’ then it will be able (in the UK) to access BBC iPlayer, ITVPlayer, etc, AND – ahem – may allow you to watch content on paid-for services without paying, or access sites where recorded episodes of paid-for content is stored by third-parties.

The boxes like the Sky/Roku/NowTV are locked to legitimate sources (we use our NowTV to watch things on the BBC iPlayer), although the Now box can be hacked to have other legit apps put on it).

Well no, kodi is software that runs on various hardware platforms. As you say originally on the xbox (as xbmc), but can also run on amazon fire hardware and hacked apple tvs, but not I believe on Roku boxes. The dedicated boxes are actually mainly android platforms. a Now TV box (locked down roku) can only have one extra app on it and most choose Plex for it’s flexibility.

Kodi can be used legitimately as a kind of plex streaming your own ripped media from a computer, however there are thousands and thousands of apps that can be installed to find premium sport, movies, porn etc. Illegal, but impossible to police.

KAT was taken down a while back – it had it’s domain seized. Copies sprang up within days, so it’s probably these replacements being blocked. The whole domain blocking seems somewhat pointless as it can be bypassed in minutes.
